Patin has worked on measurements of the Higgs boson utilising data scouting during Run3 at the CMS experiment at the LHC. There are specific production and decay modes of the Higgs Boson, predicted by the Standard Model but yet to be observed experimentally. One of them is a process involving a Higgs boson produced through gluon fusion and decayed to the b quark-antiquark pair. Despite being the most probable mode, this process has not been discovered due to the overwhelming background.
To improve the signal sensitivity, the analysis looks for a “boosted” Higgs boson with high transverse momentum. With such energy, its decayed products, b quark and antiquark, travel closely in the same direction and both of them can be clustered in the same large-radius jet with two sub-jets. This constitutes a specific signature distinguishing from the background.
